What Makes Good Teachers Good? A Cross-Case Analysis of the Connection Between Teacher Effectiveness and Student Achievement

This study examined classroom practices of effective versus less effective teachers (based on student achievement gain scores in reading and mathematics). In Phase I of the study, hierarchical linear modeling was used to assess the teacher effectiveness of 307 fifth-grade teachers in terms of student learning gains. In Phase II, 32 teachers (17 top quartile and 15 bottom quartile) participated in an in-depth cross-case analysis of their instructional and classroom management practices. Classroom observation findings (Phase II) were compared with teacher effectiveness data (Phase I) to determine the impact of selected teacher behaviors on the teachers’ overall effectiveness drawn from a single year of value-added data.
